The findings are published in the online edition of Nature Medicine by David A. Cheresh, PhD, professor of pathology in the UC San Diego School of Medicine and associate director for translational research at the Moores UCSD Cancer Center, and colleagues at the cancer center and at the University of Michigan. By delivering more of this microRNA, the scientists said, it may be possible to promote new blood vessel development in patients who have suffered tissue damage from stroke, heart attacks, or diabetes. Conversely, treating patients with the anti-miR might reduce or inhibit blood vessel development in tumors or help reduce inflammation.

The tests proved that the process simultaneously converted light and heat energy into electrical current.
